GSM Controlled Robotics

Robotics deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behavior, and/or cognition. Many of today's robots are inspired by nature contributing to the field of bio-inspired robotics.We can develop any kind of robot depending on the purpose for which we are designing it. Earlier it used to be really impossible to design a robot, but now with advancement in science and technology we are at a point that we can design a robot with the help of certain programs which we need to activate and run the robot and some electrical circuits to develop the robot.We are making a GSM controlled robot.GSM controlled robot can be made by using a microcontroller or without using a microcontroller. We have made by using a microcontroller. GSM controlled robot or SMS controlled robot is a wireless robot which performs the necessary actions by receiving a set of instructions in the form a Short Message Service (SMS). In this project we can control the robot directions like forward, backward, left and right by sending SMS from the mobile. This project mainly consists of 2 sections, one is mobile unit and the other one is robot unit. The GSM modem which is fixed at the robot receives the messages sent by the mobile and gives the instructions to the microcontroller to control the robot directions. In this project, we interface 8051 microcontroller with GSM SIM 300. The protocol used for the communication between controller and GSM modem is UART (Universal Asynchronous Receiver-Transmitter). This system continuously checks for message to take the decision for controlling the robot.
